Question 1 of 5
A nursing student questions an instructor regarding the order for fluvoxamine (Luvox) 300 mg daily for a client diagnosed with obsessive-compulsive disorder (OCD). Which instructor response is most accurate?
Correct Answer: B
Rationale: The correct answer is B because SSRI doses higher than those used for depression are often needed to effectively treat OCD due to its different neurobiology. This is because OCD involves abnormalities in serotonin transmission, and studies have shown that higher doses of SSRIs can be more effective. Choice A is incorrect because tricyclic medications are not typically used as first-line treatment for OCD. Choice C is incorrect because daytime drowsiness is not a common side effect of Luvox. Choice D is incorrect because 300 mg daily dose of Luvox is within the therapeutic range for OCD treatment.
Question 2 of 5
A patient being treated for major depression is the CEO of her own business. She has shown significant improvement and is about to be discharged after completing a course of 15 electroconvulsive therapy sessions. She will continue on SSRI medications. The patient has been counseled not to make a major business decision for a month. The rationale for this is that:
Correct Answer: B
Rationale: The correct answer is B: ECT often causes temporary memory impairment. ECT is known to cause short-term memory loss and cognitive side effects. As the patient has just completed 15 sessions of ECT, it is important to allow time for her memory and cognitive function to recover before making major decisions. Choices A, C, and D are incorrect because SSRIs typically do not cause confusion, lingering depression alone does not make a person incompetent, and the patient's need for readjustment to work pressures is not directly related to the potential memory impairment caused by ECT.
Question 3 of 5
A patient is prescribed enoxaparin. The nurse knows that low-molecular-weight heparin has what kind of half-life?
Correct Answer: A
Rationale: The correct answer is A: A longer half-life than heparin. Enoxaparin, a low-molecular-weight heparin, has a longer half-life than unfractionated heparin due to its higher bioavailability and slower clearance. Enoxaparin's longer half-life allows for less frequent dosing compared to unfractionated heparin. Choice B is incorrect because low-molecular-weight heparin has a longer half-life than unfractionated heparin. Choice C is incorrect as low-molecular-weight heparin has a longer half-life than unfractionated heparin. Choice D is incorrect as it states that the half-life of enoxaparin is four times shorter than unfractionated heparin, which is not true.
Question 4 of 5
A nurse instructs a patient taking a drug that inhibits monoamine oxidase (MAO) to avoid certain foods and drugs because of the risk of:
Correct Answer: C
Rationale: Rationale for Correct Answer (C): MAO inhibitors prevent the breakdown of monoamines, leading to increased levels of norepinephrine and tyramine. Ingesting tyramine-rich foods or drugs can cause a sudden and dangerous rise in blood pressure, resulting in a hypertensive crisis. This is because tyramine displaces norepinephrine, leading to excessive vasoconstriction and increased blood pressure. Incorrect Choices: A: Cardiac dysrhythmia is not directly associated with MAO inhibitors. B: Hypotensive shock is contradictory as MAO inhibitors increase blood pressure. D: Cardiogenic shock is not a typical risk associated with MAO inhibitors.
Question 5 of 5
A genetic counselor is called by the hospital to see patients with genetic questions or concerns. With which patient would it be most appropriate for the counselor to speak?
Correct Answer: A
Rationale: The correct answer is A because a pregnant patient with multiple sclerosis may have concerns about the impact of their condition and potential genetic risks for the baby. The genetic counselor can provide information on genetic factors, potential risks, and support options for the patient and their family. Incorrect choices: B: While mental health is important, a genetic counselor is not the most appropriate professional to address a recent suicide attempt. C: The number of drugs prescribed does not directly relate to genetic counseling needs. D: Schizophrenia and multiple hospital admissions may require psychiatric care but do not necessarily warrant genetic counseling unless there are specific genetic concerns related to the condition.
